underground electrical fault locator

Part 1: Panel indicator

 

1,Summary

TYHD-2 panel type fault indicator(be called indicator for short below) is mainly used for switch gears for locally indicate short circuit fault and earth fault and also provide wireless signal output .

2,Working principle

The principle is micro-controllers with little power consumption, micro-controllers can automatically identify fault signals from short circuit indicator and earth indicator, They can display the fault signals using LED flashing lights on the spot and output the signals by wireless.

3.

3.1 Fault indicate function

The lights on the L1,L2,L3,and Earth buttons will flash with a an interval of 4 seconds,if the short circuit fault or earth fault occur.This can be reset automatically according to the time delay set before delivery from the factory or manually reset by pressing button of “Reset/Test”.the status of low battery capacity of the indicator can be uploaded by wireless,in the meantime, The indicator will flash for low battery voltage(with 4 seconds of interval).

3.2 Reset/Test function

3.2.1 Reset: press lightly the “Reset/Test” button slightly, it will reset after all lights on in indicator

3.2.2 Self-checking:

press ““Reset/Test” button, press on L1 and L2 in turn, then let go, after all lights are on at mean time once, the corresponding address lights is on. In 10s, corresponding address lights are on again, then self-checking finished.(indicator current address refer to label number in the back).address is corresponding to L1,L2,L3,E lights by BCD code, instructions is as following table:

Address black point means the corresponding LED is on
L1(1) L2(2) L3(4) E(8)
1

8

3.2.3 L1,L2,Wireless function self-checking

press “Reset/Test” button, press on L1 and L2 and L3 in turn, then let go, the indicator will send wireless status message to upper computer, the “ battery low voltage” light will flash fast 3 times to indicate, it tells test finished. If transmission is failed, the test status will exit automatically in 1 minute. Operator also can press slightly on “Reset/Test” button to reset indicator and exit this status.

3.2.4 indicator address configure

When install the indicator, the panel indicator address should not be the same in the same RMU or switching station, if the address is same, it will result in the information transmission mixed error.each indicator labels its current address(when installed, its address also can be checked by the way of self-checking. If need to modify indicator address,please follow the following steps:press “Reset/Test” button, press on L1 and L2,L3,Earth fault lights in turn, then let go,light of “low battery voltage” flash(with an interval of 1s) and change to ready- setting state(automatically exit in 20s), press again“Reset/Test” button, lights of L1,L2,L3,Earth fault will display address (1-8)by the address sequence of BCD code, when it displays the address which requires to be configured, then let go at once,the expected address will flashing clockwise with the light of “low battery voltage”, at this time, press the button again and save this address. The operator can refer to the self-checking steps mentioned in 2.2 to check if the address written is right; if configuration is not right or cancel this configuration, please not save, the configuration

4. Function

4.1 Show short circuit fault and earth fault locally.

4.2 Self-reset ,self-reset time can be set before delivery from factory (The default value is 12 hours).

4.3 Reset manully /self-test manually is available .

4.4 address of the indicators can be configured
